How Much Should Restaurants Pay in Credit Card Processing Fees?

Card processing costs sit somewhere between 1.5% and 3.5% of a restaurant's card volume, depending on the card types your guests use, how you accept payment, and who you've signed with. 

That's a wide enough range that two restaurants doing the same revenue can differ by tens of thousands of dollars a year on fees alone. That gap is worth considering as margin, and it belongs in the same conversation as your restaurant profit margin and your monthly restaurant income statement.

This piece breaks down what makes up a processing fee, how the main pricing structures compare, and what's realistic to expect on a Canadian statement in 2026.

What's actually in a processing fee

Your statement may not even use the term “credit card processing fee.” Canadian payment providers often refer to the total cost as the merchant discount rate (MDR). You might also see processing fees, merchant fees, or discount fees. They all refer to the same bundled charge. An interchange fee is different. It’s the largest part of the MDR and goes to the card-issuing bank. If your statement only shows a single processing fee without breaking out interchange, you’re probably on a flat-rate or tiered pricing plan rather than one that itemizes the costs.

A card transaction passes through several companies before the money reaches your account, and each one takes a share. Interchange fees go to the card-issuing bank and are set by the card network based on the type of card and the level of risk. Network fees, including assessment fees, go to Visa, Mastercard, Amex, or Discover for processing the transaction. Your payment processor then adds its own charges, which may include a separate gateway fee, plus any monthly software or hardware costs.

Interchange is the part Canadian operators have the least control over, but it’s also changed the most in recent years. After a federal agreement with Visa and Mastercard, the weighted average interchange rate for eligible small and medium-sized Canadian businesses fell to about 0.95%, reducing costs by up to 27% for more than 90% of merchants that accept cards. It’s a meaningful saving, but it only applies to interchange. Network fees, processor markups, and monthly charges still vary from one provider to the next.

Corinne Pohlmann, Senior Vice President of National Affairs at the Canadian Federation of Independent Business, has estimated that credit card fees cost Canadian businesses roughly $5 billion a year in aggregate, a figure that captures just how much is riding on getting your pricing structure right rather than accepting whatever a sales rep quotes you.

Comparing the four pricing structures

Flat rate

Flat-rate pricing charges the same percentage on most transactions, with some providers applying a separate rate for Amex or card-not-present payments. It’s simple to understand and easy to budget for. You know what each transaction will cost without digging through a processing statement.

The downside is that you lose sight of what’s driving your costs. Interchange, network fees, and your processor’s markup are bundled into a single rate, so if your bill goes up, it’s hard to tell whether customers are using more premium cards or your processor has increased its margin.

Interchange plus

Interchange-plus pricing separates the processor's markup from the underlying interchange and network fees, so you see exactly what you're paying for infrastructure versus what you're paying for the processor's service. It also shows you your card mix in detail, which is useful if you want to understand how many of your guests are paying with premium rewards cards that carry higher interchange.

The trade-off is complexity. Your statement may include dozens of interchange categories, and the mix changes every month as guests pay with different cards. That makes forecasting less straightforward than with flat-rate pricing. The upside is greater transparency, but it only helps if someone on your team takes the time to review the statement.

Tiered pricing

Tiered pricing sorts transactions into buckets, usually qualified, mid-qualified, and non-qualified, with a low headline rate on the first tier and higher rates on the rest. The qualified rate is often what gets quoted upfront, which is part of the problem. Restaurants have no control over which tier a given card falls into, since that's determined by the processor's own criteria, and a disappointing number of transactions can end up downgraded to a higher tier without much explanation.

Of the four structures, tiered pricing tends to give operators the least insight into their true blended rate, and it's worth asking directly whether a quoted "tier" is actually a pricing structure or, in the case of Amex, just a naming convention for their own discount rate.

Subscription pricing

More Canadian restaurants are also considering membership pricing. Rather than charging a percentage markup, the processor charges a fixed monthly fee, while interchange and network costs pass through at close to cost. A small per-transaction fee is then added to each payment.

For a high-volume restaurant, stripping out a percentage-based markup in favour of a fixed monthly cost can add up to meaningful savings, though it shifts more of your costs into interchange and network fees while removing most percentage-based processor markup. Whether this beats interchange-plus depends on your volume, so it's worth asking any provider to model out both against your last twelve months of statements before you commit. 

What a healthy blended rate looks like

Don't compare quoted rates. Compare your blended rate, total processing cost divided by total card volume, since that's the number your statement actually produces.

For Canadian restaurants taking mostly in-person payments, a well-negotiated interchange-plus or subscription setup typically blends to 1.6% to 2.2%. Flat rate usually runs 2.6% to 3.5%, since simplicity is priced in. Tiered pricing is the trap: the quoted "qualified" rate can look like 1.5% to 1.8%, but once mid-qualified and non-qualified transactions are counted, the real blended rate often lands as high as flat rate or higher.

If your last statement blends above 2.5% and you can't explain why, that's worth a closer look.

What moves your effective rate, beyond the pricing structure

The pricing model you choose sets the baseline, but day-to-day operations determine what you pay each month.

Tips are easy to overlook. Because processing fees are charged on the full transaction value, including gratuities, higher tips also mean higher processing fees. An integrated POS records the final tip before settlement, helping ensure the right amount is processed, but it’s worth remembering that your fee total depends on tipping patterns as well as sales.

How the card is presented also matters. In-person transactions, whether tapped, dipped, or swiped, typically carry lower interchange than card-not-present transactions like phone orders or online ordering, because the card networks treat the latter as higher fraud risk. As more Canadian restaurants lean on online ordering and delivery for revenue, it's worth watching what share of volume is shifting into that higher-cost category and pricing menus or delivery fees with that in mind.

Security measures at the terminal can also affect which interchange tier a transaction qualifies for. EMV chip acceptance, tap-to-pay, and address or CVV verification on card-not-present orders all reduce fraud liability, and processors and card networks generally reward that with better rates. It's a rare case where the fraud-prevention investment and the cost-control goal point in the same direction.

If your restaurant serves a lot of tourists, especially in places like Niagara-on-the-Lake, Whistler, Banff, or Charlottetown during peak season, you’ll likely see more international cards. Those transactions usually come with extra cross-border fees on top of standard interchange, which can push up your blended processing rate without any changes to your processor or pricing model.

The Canadian regulatory layer operators can't ignore

Two developments since 2022 changed what's actually negotiable on a Canadian processing bill, and both play out differently depending on where you operate.

The first is the interchange reduction described above, which lowers the floor for most merchants regardless of province.

The second is surcharging. Since October 2022, following a class action settlement with Visa and Mastercard, merchants outside Quebec have had the legal option to pass a portion of credit card processing costs on to guests at the point of sale, capped at 2.4% or your actual effective rate, whichever is lower. Quebec is the exception. Provincial consumer protection law there effectively blocks the practice, so an operator in Trois-Rivières doesn't have the same lever available as one in Calgary or Ottawa running the identical POS setup.

Restaurants Canada has flagged real friction in the option even where it's legal. Surcharges must be disclosed at the point of entry and itemized on the receipt, staff need to be trained to explain them, and Canadian diners, unlike their counterparts in some other markets, aren't used to seeing a card fee appear on their bill. For a full-service restaurant competing on guest experience, that's a genuine cost-control-versus-hospitality trade-off, and most operators who look into surcharging ultimately decide the customer friction isn't worth the basis points recovered.

Toast's own consumer research backs up why this matters at the point of sale. Contactless card is the preferred payment method for 45.5% of Canadian diners, ahead of mobile wallets at 19.5%, cash at 16.5%, and a traditional swipe at 17%. Nearly two-thirds of transactions in a Canadian restaurant are now happening through contactless or mobile methods, which means almost every guest interaction is running through the interchange and network fee structure described above. There's very little room left to sidestep processing costs by nudging guests toward cash.

A framework for evaluating your own rate

Before signing with a processor or renewing a contract, it's worth asking a few direct questions rather than comparing headline rates alone. 

• What does your blended effective rate work out to as a percentage of total card volume, not just the quoted rate on qualified transactions. 

• Is your provider using interchange-plus or subscription pricing, and if so, does someone on your team actually review the statement monthly. 

• Are there hidden fees, statement fees, PCI penalty fees, or early termination fees, that don't map to any service you're receiving. 

• Given the post-2022 changes, does surcharging make sense for your concept and location, keeping in mind it isn't available if you operate in Quebec.

Don’t assume your processing rate is set in stone. Many processors are willing to revisit pricing after a full year of transaction history, especially if your sales volume has increased since you first signed up. Updating your EMV terminals, accepting tap to pay, and adding verification for card-not-present transactions can also help move more payments into lower-cost categories.

Nothing here is legal or tax advice, and you should check any decisions about surcharging or fee structures with your payment processor and, if needed, a financial advisor. No matter where you operate in Canada, the most important thing is knowing what you’re paying for.
